This make is really sick. Without Fast Internet and Good network, iphone is nothing but ifokut.  It can be only used for show. First of all, Mobile is for talk. In the case of Nepal's NTC's network its so so pathetic. Forget about the 3g, they even didn't met the standard of 2G. I am not discouraging the Nepal's Telecom but its the bitter fact. Its call quality is really horrible.
